TWISTING OR SPINNING MACHINE..

SPECIFICATION forming part of Letters Patent No. 787,554, dated April 18, 1905.

Application filed Tune 9, 1904. Serial No. 211,737.

To all whom it may conc-ern:

Be it known that I, HERBERT G. BEEDE, a

' citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Twisting or Spinning Machines, of which the following is a specification.

My invention relates to twisting or spinning machines for twisting or spinning yarn, and more particularly to that class of machines having a knotting attachment for making knots, loops, &c., in the yarn, shown and described in my application for a patent, Serial No. 188,681.

r1`he object of my invention is to improve upon the construction of some of the parts of the mechanism shown and described in my said application, and particularly the construction of the rocker-arms, which support the knotting guide-bar. In my said application the arms which support the knotting guidebar are detachably and rigidly attached to a rocker-shaft and are not adjustable, so that the position of the knotting guide-bar, having thereon a series of guides for the yarn, is not adjustable to vary the tension on the yarn and also to change the position of the guides.

In my improved construction I have made the knotting-guide-bar-supporting arms adjustable in the direction of their length to vary the position of the knotting guide-bar and increase or diminish the tension on the arn. I have also provided a rotary bearing for the knotting guide-bar, so that the plane or angle of the guide-bar relatively to the supporting-arms may be adjusted as desired.

My invention consists in certain novel features of construction of my improvements, as will be hereinafter'fully described.

I have shown in the drawings a detached portion of a twisting-machine corresponding to what is shown in the drawings of my said application with my improvements applied thereto.

Referring to the drawings, Figure 1 is a front view of one end of a detached portion of a twisting-machine corresponding to Fig. 1

looking in the direction of arrow c, same figure. Fig. 5 is a section on line 5 5, Fig. 3, looking in the direction of arrow d, same figure. Fig. 6 is a section on line 6 6, Fig. 3, looking in the direction of arrow e, same iigure and Fig. 7 shows the rotary bearing of the knotting guide-bar detached, with the guidebar therein. Figs. 2 to 7, inclusive, are shown on an enlarged scale. j

In the accompanying drawings, 1 is a portion of a frame of a twisting-machine.

2 is the lower-roll stand, having a bearing thereon for the end of the journal on the lower roll 3. The stand 2 has a stand 4 thereon for the top roll 5.

6 is a traverse-rod carrying the guide-wires 7 and adapted to have a traverse motion communicated thereto in any ordinary way.

8 is the upper roll, which has a bearing for the journal of the upper roll 9, above which extends the top roll 10.

11 is the upper traverse-rod, having guidewires 12 thereon. The upper traverse guidewire rod 11 is preferably rigidly connected with the lower traverse guide-Wire rod 6 by a plate or bar 13.

14 is a rocker-shaft, on which are fast the arms carrying the knotting guide-bar 15, having the guides 16 thereon.

All of the above parts are substantially of the same construction as shown and described in my said application for a patent. I will now describe my improvements. Detachably and rigidly secured upon the rocker-shaft 14 by a set-screw 17 is a block or support 18, (see Fig. 2,) forming an attaching-surface for the inner end of the supportingarms 19, (only one of which is shown,) which carry atA their outer end the knottin guideebar 15. The upper surface of the b ook 18 has a longitudinal projection 18 thereon (see Fig. 5) to receive a longitudinal recess in the under surface of the inner end of the arm 19. The block 18 also has a wedge-shaped tooth or projection 18 thereon to extend into one or the other of a corresponding-shaped recess 19 in the under surface of the inner end of the arm 19. The inner end of the arm 19 has a longitudinal slot 2() therethrough to receive a bolt 21, which has a washer 22 thereon. The bolt 21 is adapted to screw into a threaded hole in the block 18. By means of the block 18 and the slotted inner end of the arrn 19 the arm 19 may be adjusted in the direction of its length on the bl'ock 18 to make the arm longer or shorter from its point of attachment by the bolt 21 to the block 18, as desired, by simply turning out the bolt 21 and moving the supporting-arm 19 in one direction or the other and causing the extension 18 to extend into one of the recesses 19 and then screwing in the bolt 21 to bind the parts rigidly together.

The outer end of the arm 19 has a circular recess therein to receive one half of the bearing 23, which is free to rotate in said recess and is prevented from moving longitudinally therein by a stud 23, extending into a groove 24 in the recessed end of the arm 19. (See Fig. 4.) A cap 25 has a grooved recess therein to receive the other half of the bearing 23 and also has a groove 25 therein to receive the stud 23 on the other half of the bearing 23. (See Fig. 1.) The cap 25 has a vertical projection 25" thereon (see Fig. 6) which is adapted to extend into a vertical recess 19" in the outer end of the arm 19 to hold the cap in position on the end of the arm 19. A screw 26 extends loosely through a hole in the cap 25 and screws into a threaded hole in the end of the arm 19 and detachably secures the cap 25 tothe arm 19. The knotting guide-bar 15 extends between the two halves of the rotary bearing 23 and is supported thereby. In case it is desired to change the position of the knotting guidebar 15, as shown by full and broken lines in Fig. 2, to vary the position of the guide 16, the screw 26 is turned out to loosen the cap 25 and allow of the bearing 23 being rotated as desired. The screw 26 is then screwed in to bind the parts together and prevent the rotation of the bearing 23.

It will be understood that the details of construction of my improvements may be varied, if desired, and they may be used on twisting or spinning machines or for other machines where adjustable bearings are required.

The advantages of my improvements will be readily appreciated by those skilled in the art. By means of the supporting-arms 19 the knotting guide-bar 15 may be moved out or in to increase or lessen the tension on the yarn, and the position of the knotting guidebar relatively to the supporting-arm 19 may be regulated as desired to vary the position or angle of the guides for the yarn.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is-

1. In a twisting or spinning machine, the

combination with a knotting guide-bar, of a supporting-arm adjustable longitudinally, to vary the position of the guide-bar, substantially as shown and described. a

2. In a twisting or spinning machine, the combination with a rocker-shaft, and a block or support thereon, of a supporting-arm for the knotting guide-bar adjustably attached to said support, to vary the position of the guide-bar, and said guide-bar, substantially as shown and described. l

3. In a twisting or spinning machine, the combination with the supporting-arm of the knotting guide-bar, of the guide-bar, adjustably supported in said arm, to vary the position thereof, substantially as shown and described.
